Question

我将以下路线添加到我的MVC应用程序中。

routes.MapRoute("leads", "leads/{leadId}", new { controller = "Leads", action = "ViewLead" });

然而，似乎现在任何关于引导控制器的操作方法都会导致它尝试转到ViewLead操作，并且不会将id作为其动作传递。我有点失望，然后必须将以下内容添加到我的路线中，这样我就不会对我的其他操作产生异常：

    routes.MapRoute("leadIndex", "leads", new { controller = "Leads", action = "Index" });
    routes.MapRoute("leadAdd", "leads/addlead", new { controller = "Leads", action = "AddLead" });            
    routes.MapRoute("leadsSearch", "leads/searchleads", new { controller = "Leads", action = "SearchLeads" });            
    routes.MapRoute("leadsGetAll", "leads/getallleads", new { controller = "Leads", action = "GetAllLeads" });
    routes.MapRoute("leadsUpdate", "leads/updatelead", new { controller = "Leads", action = "UpdateLead" });
    routes.MapRoute("leadsRecipients", "leads/getrecipients", new { controller = "Leads", action = "GetRecipients" });

我在这里做错了吗？它似乎违反DRY原则，因为我之前没有必要指定这些路线，但现在我做了......

所有路由与lead / {leadId}路由匹配的原因是因为它匹配{string} / {string}的模式。你需要做的是添加一个约束，表明leadid是一个int。

routes.MapRoute(
    "leads", 
    "leads/{leadId}", 
    new { controller = "Leads", action = "ViewLead" },
    new { leadId = @"\d+" });

这只会匹配第二个位置的参数至少有一个或多个整数时的路径。

但是，如果您想拥有多个具有相同基础的自定义路线，请查看Phil Haack撰写的这篇文章：http://haacked.com/archive/2010/12/02/grouping-routes-part-1.aspx

希望这有帮助！
